MSDN <http://msdn.microsoft.com/library/default.asp?url=/library/en-us/vccore/html/C2558.asp> says:

Trying to copy a class whose copy constructor is explicit. Declaring a copy constructor with explicit prevents passing/returning objects of a class to/from functions.

So why someone declared it explicit? Does it compile under gcc? Resolutions under msvc point just to removing the explicit keyword.
